The critical detection point in a Physical Protection System (PPS) occurs when the remaining distance or time an adversary must cover before reaching the target exceeds the security response time. This ensures that detection happens early enough for responders to act and intervene before the attacker reaches the asset.
B and C refer to detection and interruption probabilities, which are important metrics but not the defining threshold for the critical detection point.
D (Remaining delay time) factors into the protection layers but does not define the detection threshold.

Focal length is the primary factor in determining the magnification and field of view in a camera lens. A longer focal length results in a narrower field of view and greater magnification of distant objects.
Conversely, a shorter focal length gives a wider field of view with less magnification.
A (Image device) and B/C (Lens or image format) influence compatibility and image quality, but do not directly affect magnification.

Integrity, in the context of information security, refers to ensuring data is accurate, consistent, and unaltered by unauthorized actions. Maintaining integrity prevents data manipulation or corruption, ensuring reliability for organizational decision-making.
Analysis (A) is the process of evaluating data.
Security (C) is a broader term encompassing integrity, confidentiality, and availability.
Availability (D) ensures access but does not guard against data tampering.

Quantitative analysis involves the use of numeric data to evaluate system performance. In Intrusion Detection Systems, metrics such as Probability of Detection (PD), False Alarm Rate (FAR), and Nuisance Alarm Rate (NAR) are used to objectively measure system effectiveness.
A and C are more subjective or observational.
B (Theoretical) implies modeling, not actual data evaluation.

Comprehensive Detailed Explanation
When multiple areas of a facility or operation undergo programmed supervision, their findings contribute to an aggregate operational audit. When these audits are viewed collectively, they provide a comprehensive view of the organization's overall operational effectiveness and compliance. This holistic oversight is critical for enterprise-level security governance.
